SPOT FREE CAR WASHING – SOFTENER DEIONIZER STICK
The Softener Deionizer will both soften and deionize the water to give you spot free results when washing or rinsing cars, RVs, boats, solar panels, windows, motorcycles, airplanes, trucks, boat isinglass, surgical instruments, etc. No more hand drying!
For completely spot free results, the water needs to be both softened to remove hard water minerals AND deionized to remove TDS (Total Dissolved Solids). Softened water will leave some spots but softened AND deionized water will leave no spots.
